"Jarvis's 1958 book Folk Medicine: A Vermont Doctor's Guide to Good Health was on The New York Times Best Seller list for two years,
ultimately selling over one million copies, more than 245,000 copies in a single year, and was still in print as of 2002.
Wrote one reviewer, "Pliny, the ancient Roman originator of the doctrine of signatures, used honey and vinegar to cleanse the system and promote good health. D. C. Jarvis, M.D. in Folk Medicine has re-popularized the use of honey and apple cider vinegar in modern times."
I've had this book for over 30 years - but discontinued acv bc of the taste...
